Hi Mike,

it's pointing to the same location (/opt/sphenix is a softlink). But there is a more principal problem in your approach. In order to make our offline builds self-consistent our core libraries (gsl, boost, clhep, rave,...) are copied to OFFLINE_MAIN. This guarantees that old builds (like production builds) stay usable even if we upgrade those packages. We have been doing this for PHENIX for a long time and it's been working well. Root and G4 are the exceptions because they are too large and our offline builds contain softlinks to the G4/root version which was used. But this means using those config scripts to locate 3rd party libraries is just a bad idea.

Hi Chris,

I've run into some configuration issues porting the latest to a virtual machine. It doesn't seem like the /afs locations were scrubbed from the new build the way they usually were (and of course I don't run afs on the virtual machine, nor will it be available on the grid).

The key part seems to be that the CLHEP configuration within geant4-config --libs return has the /afs directory instead of the /opt. That command gives this:

-L/afs/rhic.bnl.gov/@sys/opt/sphenix/core/clhep-2.3.2.2/lib -lCLHEP

instead of:

-L"/opt/sphenix/core/clhep-2.3.2.2/lib" -lCLHEP-2.3.2.2

as is returned by clhep-config --libs

Hi folks,

as mentioned in the software meeting our current G4 installation used an
internal CLHEP version which was incompatible with the external one used
by rave and therefore the linking failed. In order to fix this G4 had to
be recompiled against the external CLHEP library. I took the opportunity
to upgrade G4 to the next patch level. It required two minor changes to
our sources (location of the CLHEP includes and a method name change in
G4EmSaturation).

The current new build is using this new version and it can be used
together with rave and genfit.
